Posted on July 26, 2017 at 10:49Hello ALL
I cant use alarm B when the alalrm occurs the device stuck and need a hardware reset .
Alarm A is working
we have 2 software : one the USB boot for upgrade ; the other is the main program
here is the code example for Alarm A ; we use same for alarm B but we change teh register names
what is
RTC_AlarmMask_Hours ? for example I can set any hour to wake up ?
please guide me if I forget something and thank you in advanced .
code :
RTC_AlarmCmd(RTC_Alarm_A, DISABLE);
RTC_AlarmStructure.RTC_AlarmTime.RTC_H12 = RTC_H12_PM;
RTC_AlarmStructure.RTC_AlarmTime.RTC_Hours =2;
RTC_AlarmStructure.RTC_AlarmTime.RTC_Minutes =0;
RTC_AlarmStructure.RTC_AlarmTime.RTC_Seconds = 0;
RTC_AlarmStructure.RTC_AlarmDateWeekDay = 1;
RTC_AlarmStructure.RTC_AlarmDateWeekDaySel = RTC_AlarmDateWeekDaySel_Date;
RTC_AlarmStructure.RTC_AlarmMask = RTC_AlarmMask_DateWeekDay;//|RTC_AlarmMask_Hours ;
RTC_SetAlarm(RTC_Format_BIN, RTC_Alarm_A, &RTC_AlarmStructure);
PWR_WakeUpPinCmd(DISABLE);
RTC_ITConfig(RTC_IT_ALRA, DISABLE);
RTC_AlarmCmd(RTC_Alarm_A, DISABLE);
/* Clear RTC Alarm Flag */
RTC_ClearFlag(RTC_FLAG_ALRAF);
PWR_ClearFlag(PWR_FLAG_WU);
PWR_ClearFlag(PWR_FLAG_SB);
RTC_ITConfig(RTC_IT_ALRA, ENABLE);
/* Enable the Alarm A */
RTC_AlarmCmd(RTC_Alarm_A, ENABLE);
/* Clear RTC Alarm Flag */
//-----------------------------------------------
//set_alarm_b( );
PWR_WakeUpPinCmd(ENABLE);
/* Request to enter STANDBY mode (Wake Up flag is cleared in PWR_EnterSTANDBYMode function) */
PWR_EnterSTANDBYMode();
